Trevor Cox – Professor of Acoustic Engineering at the University of Salford (UK) commented: ” “The creative and fruitful working relationship between architect and acoustic consultant is key to a good design. A common mistake is for the importance of acoustics not to be considered early enough in the design. Considering acoustics too late means the cost of good sound is likely to be more expensive.”

The oriented development of the Institute of Development & Application for Sound Materials (DASM) is focusing on design consulting, research, test – measurement – assessment, adjustment, production and creation of acoustic solutions. We provide optimal support for our customers’ products, equipment, materials, works and projects. From the first foundation to the whole sustainability journey!
